Network perf analyse via iperf3 |
|
Start daemon sets
oc new-project iperf-test
oc apply -f iperf.daemonset.yaml
oc create sa hostnetwork
oc adm policy add-scc-to-user hostnetwork-v2 -z hostnetwork
oc apply -f iperf-hostnetwork.daemonset.yaml
Run network performance tests via:
# Example ucs56 -> ucs57
$ oc get pods -o wide | grep ucs
